Main description (English)

Today's fashion industry is increasingly imposing its choice in using computer technologies for garment design (both for design and patternmaking). One of the major challenges in this case concerns the 3D representation of garments. 3D CAD systems, used in the fashion industry, can be generally divided into two groups. The first one uses '2D to 3D' approach, creating prior digital 2D patterns, which next can be draped around a 3D body. The second one applies '3D to 2D' approach where the garment is designed onto three dimensional human figures, which further can be transformed into flat 2D patterns. Some CAD systems combine these two approaches. Compared to other mechanical product, garment CAD has to address some special issues. Firstly, it models soft material with low bending stiffness rather than rigid solid objects. Secondly, garment components such as collar and sleeve, are assembled together following specific pattern-making rules which are totally different from the conventional assembly methods. Thirdly, while the garment is constructed from 2D patterns, the quality of fit is evaluated on 3D human models. Based on these observations, garment CAD is a unique research area that has attracted considerable attentions. In this study, we will overview 3D Fashion Design Software CLO and her possibilities for an effective application. Keywords: 3D CAD systems, fashion design, patternmaking
